Where to place the main gear is the probable reason the plane is a tail dragger. I don't see any simple place on mine to add the main gear and linkage. Of course, you could remove the motro and add it there then try and figure out how to install a mount over it and then the motor. The extra weight here would most likely move the CG enough so you wouldn't have to add extra weight. But, this all seems senseless. Maybe someone can come up with a mod that would not add extra weight or a least minimual weight.
